Ceramic Firing Techniques Course

Lesson 1 • Kiln Safety Fundamentals

Covers ventilation requirements, protective equipment, and emergency procedures for all kiln types. Safe practice is a prerequisite before students operate any kiln independently.

Lesson 2 • Reading Pyrometric Cones

Teaches cone numbering, placement, and interpretation as heat-work indicators. Accurate cone reading is the primary quality-control skill used throughout the course.

Lesson 3 • Heat and Ceramic Transformation

Traces physical and chemical changes from water smoking through vitrification. Links temperature milestones to observable clay behavior students will monitor during firing.

Lesson 4 • Clay Bodies and Their Properties

Examines earthenware, stoneware, and porcelain compositions and their firing ranges. Establishes material literacy needed for every subsequent firing decision.

Lesson 1 • Diagnosing Bisque Defects

Identifies cracking, bloating, and carbon trapping causes and links each to schedule or preparation errors. Systematic diagnosis skills apply to every firing type in the course.

Lesson 2 • Purpose and Goals of Bisque Firing

Defines bisque firing's role in removing organic matter and creating a porous surface for glazing. Clarifies why bisque temperature selection affects glaze adhesion in later stages.

Lesson 3 • Loading the Bisque Kiln

Teaches stacking strategies that maximize load density while protecting fragile greenware. Efficient loading reduces energy cost and is foundational to production workflows.

Lesson 4 • Greenware Preparation and Drying

Addresses moisture content assessment and controlled drying to prevent cracking during early firing. Proper preparation directly reduces bisque losses and kiln downtime.

Lesson 1 • Glaze Ingredients and Their Roles

Breaks down silica, alumina, and flux functions within a glaze melt. Understanding ingredient roles enables informed adjustments to commercial and studio glaze recipes.

Lesson 2 • Reading and Adjusting Glaze Recipes

Introduces unity molecular formula and limit formulas as diagnostic tools for glaze stability. Students learn to modify recipes for desired surface, color, and firing range.

Lesson 3 • Glaze Application Techniques

Teaches dipping, pouring, brushing, and spraying methods with attention to coat thickness control. Each method suits different production scales and surface design intentions.

Lesson 4 • Glaze Testing and Documentation

Establishes tile-testing protocols and record-keeping systems for building a reliable glaze library. Systematic testing prevents costly kiln-load failures in production settings.

Lesson 1 • Reading Glaze Surface Results

Trains visual and tactile assessment of matte, satin, and gloss surfaces against intended outcomes. Surface literacy enables rapid diagnosis and schedule refinement after each firing.

Lesson 2 • Electric Kiln Controls and Programming

Covers manual, digital, and programmable controller interfaces for setting ramp-hold schedules. Controller fluency is the operational core of electric kiln glaze firing.

Lesson 3 • Troubleshooting Glaze Defects

Maps crawling, crazing, pinholing, and blistering to their root causes in glaze chemistry or schedule. Systematic defect resolution reduces material waste and improves production consistency.

Lesson 4 • Glaze Kiln Loading Strategies

Addresses foot-ring clearance, glaze drip protection, and heat distribution in glaze loads. Proper loading prevents kiln damage and ensures even color development across the load.

Lesson 1 • Reduction Glaze Effects

Profiles celadon, tenmoku, copper red, and iron-saturate glazes and their atmospheric requirements. Students connect atmosphere management skills to specific aesthetic and chemical outcomes.

Lesson 2 • Cooling and Post-Firing Atmosphere

Covers reduction cooling, oxidation flashing, and safe kiln shutdown after peak temperature. Post-firing atmosphere choices affect final color and surface quality of reduction glazes.

Lesson 3 • Combustion and Atmosphere Principles

Explains oxidation, neutral, and reduction atmospheres through combustion chemistry. Atmosphere control is the defining variable that separates gas firing from electric firing outcomes.

Lesson 4 • Introducing and Sustaining Reduction

Teaches when and how to shift from oxidation to reduction and maintain consistent atmosphere. Timing and depth of reduction directly determine iron and copper glaze color outcomes.

Lesson 1 • Raku Firing Process

Covers rapid heating, glowing extraction, and post-firing reduction in combustible materials. Raku demands real-time decision-making skills that sharpen overall kiln-side responsiveness.

Lesson 2 • Saggar Firing Techniques

Explains saggar construction, combustible packing materials, and their effects on surface color. Saggar firing bridges pit-fire intuition with the controlled environment of kiln firing.

Lesson 3 • Health and Safety in Alternative Firing

Addresses fume hazards, burn risks, and site requirements specific to open and atmospheric firings. Safety protocols here extend and reinforce the foundational safety chapter for field conditions.

Lesson 4 • Pit and Barrel Firing

Teaches fuel selection, pit construction, and combustion management for low-temperature surface effects. Pit firing develops intuitive fire-reading skills applicable to wood and soda firing.

Lesson 1 • Crew Coordination and Firing Records

Addresses shift scheduling, communication protocols, and data logging for community wood firings. Organized crew management ensures safety and provides data for improving future firings.

Lesson 2 • Stoking Cycles and Temperature Management

Develops stoking schedules, reduction phases, and overnight management for multi-day firings. Consistent stoking rhythm is the primary skill for achieving even temperature and ash effects.

Lesson 3 • Wood Kiln Design and Principles

Surveys anagama, noborigama, and bourry box designs and their draft and ash-deposit characteristics. Design knowledge informs loading and stoking decisions throughout the firing.

Lesson 4 • Loading for Wood Firing

Teaches placement strategies that exploit flame path, ash deposit zones, and temperature gradients. Strategic loading transforms kiln variables into intentional surface effects.

Lesson 1 • Energy Efficiency in Firing

Analyzes load density, insulation, and schedule optimization strategies to reduce energy consumption. Efficiency improvements lower operating costs and reduce the environmental footprint of studio firing.

Lesson 2 • Statistical Quality Control for Production

Introduces defect tracking, yield rate calculation, and root-cause analysis for production ceramic studios. Data-driven quality control reduces waste and supports consistent client deliverables.

Lesson 3 • Developing a Personal Firing Program

Guides students in synthesizing course learning into a documented, repeatable personal firing system. A personal firing program is the professional deliverable that demonstrates full course mastery.

Lesson 4 • Designing Custom Firing Schedules

Applies clay body, glaze, and kiln data to engineer schedules for specific aesthetic and functional goals. Custom schedule design is the capstone technical skill of the core curriculum.
